Asuragen’s lab test for spinal muscular atrophy (SMA) is as robust and accurate at identifying carriers of the disease and diagnosing patients as more traditional methods, a study shows. The diagnostic test — called AmplideX PCR/CE SMA Plus Kit — was validated independently in four labs and showed over…

Blood levels of a stress-induced protein are significantly higher in young spinal muscular atrophy (SMA) patients and associate with levels of a nerve cell damage biomarker, a study shows. These findings from untreated SMA patients suggest that this protein, called heat shock 70kDa protein 7 (HSP70B), may be a…

Apitegromab, Scholar Rock’s muscle-directed therapy for spinal muscular atrophy (SMA), was granted a fast track designation by the U.S. Food and Drug Administration. “We are delighted to receive Fast Track designation and look forward to working closely with the FDA towards our aim of establishing apitegromab as…

The number of copies of the “backup” SMN2 gene and a rare genetic variant in this gene influence disease severity in people with spinal muscular atrophy (SMA), according to data from more than 2,000 people involved in a free SMA genetic testing program. Launched in 2018 by…

Spinal muscular atrophy (SMA) patients may at a fourfold greater risk of hydrocephalus, or abnormal accumulation of cerebrospinal fluid (CSF) in the brain, than their healthy peers, a large U.S. health record-based study suggests. Data also showed that patients younger than 2 years, those most likely to have more severe…

Apitegromab, Scholar Rock’s muscle-directed therapy for spinal muscular atrophy (SMA), was generally safe and showed dose-dependent accumulation and clearance of the inactive form of myostatin, a muscle growth suppressor, in healthy volunteers, according to data from a Phase 1 clinical trial. These findings, published in the journal Advanced…

Cure SMA is offering free “independence assistance packages” to teenagers and adults with spinal muscular atrophy (SMA) in the U.S. to assist with everyday living or to help make living on their own possible. The Teen & Adult Independence Assistance Package is meant to supplement the nonprofit organization’s…

The blood levels of neurofilaments — a marker of nerve cell damage — may serve as a disease onset and treatment response biomarker in infants with spinal muscular atrophy (SMA) type 1, but not in older patients with milder disease forms, a study suggests. These findings add to previous studies…

Novartis Gene Therapies has added thrombotic microangiopathy (TMA) — a rare condition characterized by blood abnormalities — to the list of safety concerns with use of Zolgensma in children with spinal muscular atrophy (SMA). This decision was driven by reports of six confirmed cases of TMA within one to two…

Sex and the number of copies of the “backup” SMN2 gene influence both the age of symptom onset and the risk of losing the ability to walk in people with spinal muscular atrophy (SMA) type 3, according to a Polish registry study. The data also confirmed the notion…
